Permissions

Stars registers granular Craft user permissions across three areas — reviews, comments, and the blocklist. Assign them per user group under Settings → Users. Admin users have all permissions by default.

Reviews

Permission	Description
`stars:viewReviews`	View the Reviews section in the CP
`stars:manageReviews`	Create and edit reviews
`stars:moderateReviews`	Approve, reject, and mark as spam
`stars:respondToReviews`	Add admin responses
`stars:deleteReviews`	Delete reviews

Comments

Permission	Description
`stars:viewComments`	View the Comments section in the CP
`stars:manageComments`	Create and edit comments
`stars:moderateComments`	Approve, reject, and mark as spam
`stars:replyToComments`	Reply to comments from the CP
`stars:deleteComments`	Delete comments

Blocklist

Permission	Description
`stars:manageBlocklist`	Manage blocked submitters (by email, IP, or user ID)

The blocklist is enforced on both review and comment submission. Use the “Block Author” bulk action from any element index to quickly block a submitter.

Events

Reviews and comments are standard Craft elements, so you can hook into their lifecycle with the usual element events:

use craft\events\ModelEvent;
use justinholtweb\stars\elements\Review;
use yii\base\Event;

Event::on(Review::class, Review::EVENT_AFTER_SAVE, function(ModelEvent $event) {
    /** @var Review $review */
    $review = $event->sender;
    // Your logic here
});
